[Enhancement]: Add `cre login` details if you're ssh'd into another box

### What would you like us to improve?

If you run `cre login`, you'll get a callback URL to your localhost. It would be great if we could tell users they can use an ssh tunnel to get the callback url.

ie:
```
ssh me@my_ip -L 53682:localhost:53682 
```

Then, the callback URL for `cre login` will open in their terminal.

### How important it is?

Not super important at all, but easy
